Does anyone know where i can get hold of a pair of inserts to fit Traxxas Maxx tyres - TRX 4973 (fit 3.8" wheels) that were originally fitted to my Traxxas Revo 3.3 from new? I've taken my tyres off the wheels to inspect them and as i suspected, the foam inserts have degraded considerably which caused the tyres to lie flat on to the wheel rims with the weight of the truck on them. I've looked on the internet for inserts and at my lhs but no luck...? i find it very strange that no where sells inserts specifically for them and similar tyres. My tyre dimensions are 30cm inner diameter, 50cm outer diameter (2cm thick) and 70cm width.
Any help would be much appreciated,,,
